I am attempting to calculate the position of a point after it has been rotated
I have been using an algorithm but I am getting incorrect values which makes me think I am using the incorrect algorithm or incorrect values.
What algorithm and values should I use to find the position of the green dot?
My calculation is here:
x = -6 y = 349 0 = -25 x' = x*cos(0) - y*sin(0) y' = x*sin(0) + y*cos(0) x' = (-5.44) - (-147.49) y' = (2.54) + (316.30) x' = 142.05 y' = 318.84 // Isn't that really wrong shdn't it be around 0,349 for the answer?
